New LS1 Owners - Newbie Tech - Wiring harness

Can anyone tell me how usable a complete wiring harness, computer, controller, modules, relays and fuses would be for a motor swap from 84 vette tune port to LS1?

Thanks

Hybrids & Conversion section can better answer that.

if you want to install a ls motor in a 84 vette the harness would be needed .
